Great news! Your team has come up with a new radio technology—one that may have the same impact as Wi-Fi or Bluetooth. Management loves it, funding is in place, patent applications are filed, production is lined up, and marketing is ready to go. This will be huge.

Or maybe not. Your invention could be illegal in the United States. That's an enormous disadvantage in today's global marketplace.

Nelson Sepúlveda was sitting in the stands at Spartan Stadium, watching his hometown Michigan State players bash heads with their cross-state football rivals from the University of Michigan, when he had a scientific epiphany.

Perhaps the nanotechnologies he had been working on for years—paper-thin devices known as ferroelectret nanogenerators that convert mechanical energy into electrical energy—could help save these athletes from the ravages of traumatic brain injury.

As 5G evolves into 6G networks, it will be critical that it adopt the most energy-efficient technologies to reduce carbon emissions and our dependence on non-renewable resources.

In terms of increased sustainability, 6G will need to aim directly at lessening its overall environmental impact, including water consumption, raw material sourcing, and waste handling. But it is also important to consider the indirect impact of 6G networks can have on sustainability by conserving resources and minimizing waste in either existing use-cases or novel use-cases.
